Here are some tips to help improve your stamina and lasting power during sexual intercourse with your wife:

1. Practice Kegel exercises: These exercises can help strengthen the pelvic floor muscles, which can improve control over ejaculation.
2. Use condoms: Condoms can help reduce sensation and delay ejaculation.
3. Try the stop-start technique: This technique involves stopping sexual stimulation just before ejaculation and then waiting until the urge to ejaculate passes before resuming stimulation.
4. Take breaks during sex: Taking short breaks during sex can help delay ejaculation and prolong the sexual experience.
5. Consider medication: Certain medications, such as selective serotonin reuptake inhibitors (SSRIs), can delay ejaculation. However, it is important to speak with a doctor before starting any new medication.
6. Communicate with your partner: Talk to your wife about your concerns and work together to find solutions that are satisfying for both of you.
7. Manage stress and anxiety: High levels of stress and anxiety can affect sexual performance. Try relaxation techniques such as deep breathing, meditation, or yoga to help manage stress.
8. Maintain a healthy lifestyle: Regular exercise, a balanced diet, and adequate sleep can all improve overall health and sexual function.
9. Seek professional help: If you are experiencing premature ejaculation or other sexual dysfunction, consider seeking help from a healthcare professional or sex therapist. They can provide you with a personalized treatment plan and support.
